Once you’ve figured out which seeds are right for you, you need to decide how many seeds to purchase. Regardless of the strain or type of seed, you should have an idea of how many plants you want to grow. It’s also a good idea to circle back to your area’s laws and check the number of plants you’re legally allowed to grow.
In addition to deciding between indica, sativa, and hybrid, you should also figure out which specific strain you want to grow. If you are not sure which marijuana strain you want to grow, or you’re curious to learn about other strains you might not be familiar with, browse through the digital catalogs of reputable seed banks online and read about the various strains currently available. The best seed banks will have plenty of helpful information.
When you’ve decided which strain to grow, do a bit of research to familiarize yourself with the unique cultivation needs of that strain. While there are general guidelines for growing any type of cannabis, each strain has its own specific needs. Some strains do better in specific parts of the world or climates. Growing a strain that is well-suited to your climate will make it easier on you and the plants while giving you better odds of a successful harvest. If you aren’t certain what strain you want to grow, you can always give mixed packs of seeds a try, though it may be difficult to replicate any successes.
However you go about buying cannabis seeds, you need to plan ahead. In many ways, successful germination and eventual harvest depend on getting the right seeds upfront. Fortunately, the cannabis industry is now offering an incredibly broad selection of seeds to choose from. Here are some of the most important factors you need to think about to ensure that the marijuana seeds you buy will meet your needs and objectives.
In many ways, buying high-quality seeds is very much like buying other items related to cannabis. Even in places where weed is legal, seeds are generally considered cannabis products the same as flower, edibles, oils, and anything else coming from the cannabis plant. For that reason, always pay very close attention to the legal status of marijuana seeds in your area.

The difference between male and female seeds is important for growers. To get big harvests of smokable buds, you want only female plants. Male plants, on the other hand, can cause a lot of problems as they will pollinate the female flowers, which makes the buds produce seeds. While some people argue for the usefulness of male cannabis plants, most growers are primarily interested in big, seed-free flowers from female plants.
When growing regular seeds, some won’t germinate and some will have to be discarded because they’ll turn out to be males. With feminized seeds, some won’t germinate, but a higher percentage of them will turn into flowering plants because there won’t be any males.
When you grow any amount of seeds, a percentage of them won’t germinate, even if you get them from a reputable breeder. Always count on a few not germinating or dying off, or roughly 1/4 of the total you put in the ground.
Autoflower plants change from the vegetative to flowering state with age, not the changing of their light cycle. They have a short grow-to-harvest time and can be ready to harvest in as little as 2 ½ to 3 months from when you put the seeds in the ground. The downside is that, typically, they are less potent, but autoflower seeds are great for people who want to grow cannabis but don’t want to spend a lot of time doing it.
How much do marijuana seeds cost?
The first couple months of the year is a great time to start planning your cannabis garden to get a head start on the outdoor growing season, which roughly runs from March to November, depending on where you live.
Before you purchase seeds online, you’ll need to figure out what strain you want to grow and what breeder you want to buy from.
If you grow some seeds and like the results, try growing another strain from that same breeder and see how it goes.
If you want six total cannabis plants to harvest for buds and are growing from regular seeds, start with about 4 times as many, or 24 seeds. Some won’t germinate and some will turn out to be males, and then you’ll want to discard down to the six best phenotypes. If growing feminized seeds, you can probably start with about twice as many seeds in this case (about 12); a couple won’t germinate, and then discard down to the six best phenotypes.
Seeds are the result of pollination. That means the seedy cannabis buds (which come from a female plant) may have come into contact with pollen from a male plant. Therefore, it’s possible the grower didn’t identify and remove all the male plants before the released pollen. It’s also possible that the plant self-pollinated (sometimes called herming) which is often the result of plant stress during the budding phase but can also be caused by genetics.
What does it mean to find seeds in your marijuana buds? Is it something to be worried about?
If it’s very seedy the buds may not feel as potent, though a few seeds here and there won’t make much difference in potency. The main problem with seedy weed is that you are getting less smokeable bud for the amount of total mass there. If it is seedless, you will get a lot more bang for your buck. Seedless bud (sinsemilla) is considered to be the highest quality and most potent type of weed.
Does it mean the weed is bad?
I’ve seen some growers get impressive results with bagseed, but overall results seem to be hit or miss. Plants can grow in odd ways and often either the yields or quality isn’t as expected. The problem is that seeds often don’t “breed true” to the buds that they came from. That is why many growers either stick to clones (which are exactly the same as the “mother” plant) or purchase seeds of a stabilized strain from a trustworthy breeder, where each of the plants will grow the way you expect, and buds more consistently have the smell, yield and potency they’re supposed to.
There’s a seed in my bud!
It should be dark and relatively hard. Very pale or white seeds, that can be easily crushed between the fingers, usually won’t sprout. However, I have been surprised to find some very flimsy seeds sprout and produce amazing plants (we aren’t breeding them for hard seeds after all) so when in doubt, I highly recommend doing the true test to see if the seed is viable – try to germinate the seed and see if it sprouts!
